FRIEDREICH’S ATAXIA, EDTA BLOOD

What is Friedreich’s Ataxia test?

The Friedreich’s Ataxia, EDTA Blood test is a genetic test performed on a blood sample collected in an EDTA tube to detect mutations in the FXN gene. These mutations cause Friedreich’s ataxia, a hereditary neurodegenerative disorder characterized by progressive loss of coordination and muscle strength. It also quantify frataxin protein levels as a biochemical correlate of disease status.

Why consider Friedreich’s Ataxia test?

• To confirm a diagnosis of Friedreich’s ataxia in individuals showing symptoms such as gait disturbance, muscle weakness, and speech difficulties.
• To differentiate Friedreich’s ataxia from other types of hereditary ataxias.
• To provide information for genetic counseling and family planning.
• To assist in early diagnosis, which can help in managing symptoms and improving quality of life.

Who should get tested for Friedreich’s Ataxia test?

• Individuals presenting symptoms consistent with Friedreich’s ataxia (progressive ataxia, cardiomyopathy, scoliosis, etc.).
• People with a family history of Friedreich’s ataxia or related neurological disorders.
• Healthcare providers may recommend this test for patients with unexplained neurological symptoms suggestive of this condition.

More Information about Friedreich’s Ataxia test

OTHER NAMES: FXN gene mutation test, Friedreich ataxia genetic test, Hereditary ataxia genetic testing

Friedreich’s Ataxia (FA) is a rare inherited neurodegenerative disorder that primarily affects the nervous system and the heart. It causes progressive damage to the spinal cord and peripheral nerves, leading to impaired muscle coordination (ataxia) and weakness. It is inherited in an autosomal recessive pattern, meaning a person must inherit two mutated copies (one from each parent) to develop the condition. Diagnosis is confirmed through genetic testing for FXN gene mutations. Regular monitoring of heart function and other complications is important.
